Let's make all of these part of PageLoadMetricsStructTraitsTest with more
descriptive names for each than 'Basic', for example
TEST(PageLoadMetricsStructTraitsTest, DocumentTiming) {
...
}
TEST(PageLoadMetricsStructTraitsTest, PaintTiming) {
...
}

Done. I don't think these names are more descriptive, so I made them to
TEST(PageLoadMetricsStructTraitsTest, DocumentTimingBasic).
